The authors selected 9 professional volleyball players (the volleyball group) and 11 non volleyball players (the control group) from provincial teenage teams, and used a 64-row spiral CT scanner to scan the wrists of the players and reconstruct a 3D image of their wrists, measured the volumes and CT values (bone densities) of car-pal bones, and revealed the following findings: as compared with carpal bones of the players in the control group, the volumes of the scaphoideums and trapezoideums of the right hands and the scaphoideums, trapeziums and tra-pezoideums of the left hands of the players in the volleyball group were significantly higher (P<0.05); the CT values of the triquetrums, pisiforms, trapeziums and hamatums of the right hands and the hamatums of the left hands of the players in the volleyball group were significantly smaller than those of the players in the control group (P<0.05); there was no significant difference in carpal bones and CT values between the right hands and left hands of the players in the volleyball group (P>0.05). The said findings indicate the followings: volleyball can increase the vol-umes and lower the densities of some carpal bones of male teenage players; the morphological structures of carpal bones of the hands of non spiker volleyball players have changes similar to those occurring to spikers. |
